2018 Toyota Sienna Tire Information

Apart from finding the right tire size, there are a couple of other factors to consider when buying Toyota Sienna tires like how and where you drive, and how much you want to spend. Think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience when evaluating your driving conditions. Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one for winter and one for summer. Other drivers buy one set of all-season tires instead. That way they don't have to return to the tire shop and their vehicle is always ready for sun, rain, and light snow!

Driving style is next on the list to think about when buying tires. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Toyota Sienna tires online.

2018 Toyota Sienna Tire Questions

  • Why check Toyota tire inflation? A small decrease in tire pressure can have a big impact on your driving. Maintaining proper tire pressure can help improve braking time, increase fuel economy, and boost tire lifespan.
  • What do the tire sidewall numbers mean for my Toyota Sienna? Your tire sidewall gives you information about load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to one of our tire technicians to learn how to read the numbers on your tire!
  • Is there an easy way to check Toyota tire tread depth? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny. Hold the penny so that Abraham Lincoln is facing you, then place your penny into a tread groove upside down. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Toyota Sienna tires. Grab a penny. Hold the so that Abe Lincon's head is facing you and his hair is pointing toward the ground. Then, place the penny into a tread groove.

2018 Toyota Sienna Brake Repair

Your Toyota Sienna engine may be strong and reliable. But if you can't stop it, then it's scrap metal. If you notice your brakes are squeaking or not working well, don’t wait!

Toyota Sienna Brakes Questions

  • What is causing my Sienna to shake when I brake? Your Sienna could shake when you brake due to worn brake pads or rotors, warped rotors, loose or worn suspension components, or faulty brake calipers. You can always schedule a free brake inspection at the first sign of strange brake behavior.
  • How long should my Sienna brake pads last? Brake pads generally last between 30,000 and 40,000 miles. Your driving can affect how long your Sienna brake pads last, though. For example, mainly driving on highways and gradually braking can help increase the lifespan of your brake pads, and carrying hefty loads or riding your brakes can shorten it.
  • Is it bad if my Sienna is leaking brake fluid when off? Your Sienna has a closed hydraulic brake system, meaning you should not have a brake fluid leak under normal conditions. However, parts of your brake system can wear out over time or become damaged, which can lead to a brake fluid leak.

Repairing Your Toyota Sienna Drivetrain

We can take care of most 2018 Toyota Sienna drivetrain components Your Toyota Sienna may need driveshaft attention if you feel heavy vibrations in your floorboards, clunks when shifting, resistance when turning, or vibration as your vehicle accelerates.

Questions About 2018 Toyota Sienna

  • What are the symptoms of a damaged Toyota drivetrain system? Your Toyota Sienna drivetrain might be damaged if you notice strange noises from the rear of your vehicle, see fluid leaking, or have issues turning.
  • Why is my Sienna malfunction indicator light (MIL) on? Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your Sienna’s malfunction warning light, or better known as the check engine light, to illuminate.
  • Is a drivetrain malfunction in my Sienna serious? A drivetrain malfunction in your Sienna should never be taken lightly. Driving with a malfunctioning drivetrain can put you in danger and lead to further vehicle damage, so it's essential to have a qualified mechanic assess and repair the problem as soon as possible.

2018 Toyota Sienna Alignment Services

Alignment services involve precise adjustments to your Toyota Sienna’s suspension system, the connection between the vehicle and the wheels. In an alignment service, calculated changes are made to the angles of your tires. This is so that your tires hit the road at an optimal angle for your vehicle’s performance — just as Toyota intended. Bring your 2018 Toyota Sienna in for a wheel alignment and we'll start with an alignment check. If needed, we'll adjust your wheel alignment angles to match Toyota recommendations.

Toyota Sienna Alignment Questions

  • Are there road conditions that can hurt my Toyota Sienna alignment? Potholes and uneven roads can knock your car out of alignment, so stay aware of the road ahead and adjust your speed (or avoid these obstacles whenever it’s safely possible).
  • When should you get a wheel alignment for your Sienna? Generally, it’s wise to have your alignment looked at around every 6,000 miles or 6 months, whichever happens first. You should check your Sienna owner’s manual to verify Toyota’s suggested interval.
  • Does getting new Sienna tires mean you need an alignment? While you don’t necessarily need to get an alignment when putting new tires on your Sienna, it’s still a good idea. Ensuring your wheels are properly aligned can help support optimal handling, tire wear, and fuel efficiency.

Questions About 2018 Toyota Sienna Engines

  • Why does the check engine light come on when I start my Sienna? It’s usually normal for your check engine light to turn on upon ignition. This is just your Sienna testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.
  • Why does my Toyota engine sound different?  Strange under-the-hood noises can point to problems within your Toyota Sienna engine. Tapping or knocking could mean you need an oil change. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing may be caused by a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.
  • What could damage my Toyota Sienna engine?  Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Tire Repair for Your 2018 Toyota Sienna

Firestone Complete Auto Care is here for you when your 2018 Toyota Sienna needs flat tire repair or inspection. There’s a chance your tire could be plugged and patched (rather than replaced). Our technicians can inspect your tire and let you know if it is safe to repair. We’ll begin by taking a look at where the damage is, the type and extent of the tire damage, and how all of your tires are wearing.

If a repair on your 2018 Toyota Sienna tire is feasible and safe, we’ll get to work on the steps to fix it: (1) Take the tire off the wheel for easy inspection, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Frequently Asked Toyota Sienna Tire Repair Questions

  • Can I drive my Toyota on a flat tire? A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your Sienna as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!
  • Can I use an emergency/temporary sealant to fix my Toyota's flat tire? Temporary sealants will solve your problem… for a little bit. If you’ve seen temporary or emergency tire sealant before (it usually comes in a can), it can be tempting to turn to this as a solution for your flat tire. Keep in mind that these fixes could buy you some time to get to Firestone Complete Auto Care for a proper repair, but they could also cause some harm in the process (for example, damage to your TPMS). Plus, using a product like this could void your tire warranty.
  • Why do the tires on my Sienna keep losing air? Your Sienna tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

2018 Toyota Sienna Maintenance Q&A

  • When should I have Toyota Sienna alignment checked?  Check your car for pothole damage! If you’ve recently hit a pothole (or even if you don’t remember hitting one… they can be sneaky!) check your tire treads, tire sidewalls, and wheels for damage. Potholes can also knock your car out of alignment, so have your alignment checked if you suspect you’ve driven over a rough patch of road lately.
  • When does my Toyota Sienna need high mileage oil?  Got 75,000+ miles on the odometer? Consider high mileage motor oil. High mileage oil is formulated to address the specific problems encountered by high mileage vehicles, or those with more than 75,000 miles. It can help reduce oil consumption, smoke, and emissions from older Toyota Sienna engines.
  • Why are my Toyota dashboard lights on?  Don't ignore dashboard warning lights! Bring your Toyota Sienna in for a diagnostic code scan as soon as a dashboard warning light flashes on, whether it's your check engine or battery light. Dashboard lights alert you to trouble under the hood.

Answers to Your Toyota Sienna Car Battery Questions

  • Why won’t my Toyota Sienna battery hold a charge? A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have been leaving your car doors ajar and the cabin light at night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.
  • How long do car batteries last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • What is the white, crusty stuff around my Sienna’s battery post?  If you notice white, crusty stuff around the battery terminals of your Sienna, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your Sienna’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

Oil Changes for 2018 Toyota Sienna

Toyota recommends changing your 2018 Sienna’s oil at regular intervals. Outside of Toyota-recommended oil change intervals, your Sienna may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by Toyota if you regularly haul heavy loads, drive in dusty terrain, adventure off-road, or go at low speeds on long distance trips.

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 2018 Toyota Sienna motor oil at Firestone Complete Auto Care. Check your owner's manual and talk with a technician to select the right Toyota Sienna oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. During an oil change, one of our techs will change your Sienna’s oil, replace and recycle your used oil and oil filter, inspect all of your other filters, refill vital car fluids, and perform a free inspection on the rest of your vehicle. Get professional engine care by making an oil change appointment for your Sienna today.

2018 Toyota Sienna Oil Change Q&A

  • Why is my Toyota Sienna oil light illuminated?  If you’re overdue for an oil change, it might trigger your Toyota Sienna oil change reminder light. If the oil pressure light is illuminated, it could be due to low engine oil, a failing oil pump, a malfunctioning oil pressure sensor, or a clogged oil filter.
  • Can I change my Toyota Sienna oil at home?  First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also helps your car perform down the road.
  • Why is my Toyota Sienna spewing blue or gray exhaust smoke?  Your engine could be burning oil due to a leak.  It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.

Engine Tune-Up Service for Your 2018 Toyota Sienna

Routine engine tune-ups can bring power back to your Sienna. The Firestone Complete Auto Care location in your community offers several Toyota Sienna engine tune-up services. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your Sienna. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Sienna's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your Sienna can determine what kind of service it needs. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.

2018 Toyota Sienna Engine Tune-Up Q&A

  • What happens if my Toyota Sienna spark plugs fail?  Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What do I do if I see a pool of liquid under my Toyota Sienna? Don't ignore puddles of fluid under your Toyota Sienna. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • How often do Toyota Sienna fuel injectors need to be cleaned? The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

2018 Toyota Sienna Suspension Service & Repair

When you first drove your 2018 Toyota Sienna, you and your passengers probably enjoyed a ride that was smooth and balanced. Lately, though, your ride’s been feeling a little bumpy. Maybe your Sienna bounces, drifts to one side, or makes a weird sound when you drive over a speed bump or turn. The first sign of problems is a good time to bring your 2018 Toyota Sienna in for suspension and steering service. We’ll get to the source of your car problems and, if your Sienna suspension system needs repair, we’ll go over the services you need and how much they will cost before we do any work.

2018 Sienna Steering & Suspension Q&A

  • Why does my Toyota Sienna bounce so much?  If it feels like you’re on a trampoline every time your Sienna goes over a bump or dip, you may have a problem with your struts or shocks. Faulty shocks and struts can’t properly absorb road bumps, leading to a bouncy ride.
  • Why does my Sienna tilt forward when I hit the brakes?  The forward dip in the front end of your Sienna when you brake is caused by the weight and momentum transferring to the front wheels. If your suspension system is in bad shape, it can fail to distribute this force, leading your front end to dip further downward.
  • What role do tire pressure and tread depth play in my Toyota's suspension?  Keeping your tires properly inflated can help reduce strain on the suspension, and also help you notice when you need new tires. A tire that doesn't have an adequate amount of tread can't grip the road or function as well as the manufacturer intended.

2018 Toyota Sienna A/C Service Near You

Our technicians will work to solve your 2018 Toyota Sienna A/C problems to the best of their ability. In this A/C performance inspection, we’ll check out the current condition of your 2018 Toyota Sienna A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure.

When we perform an A/C repair on your 2018 Toyota Sienna, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Toyota guidelines. The A/C system is recharged with new refrigerant.

Questions About 2018 Toyota Sienna A/C Systems

  • Why is my Sienna A/C blowing hot air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • How does my A/C system get a leak? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Sienna’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why does my Sienna’s A/C only work when the car is moving?  A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your Sienna is moving. You may be low on refrigerant, or the cooling fan could be faulty.

2018 Toyota Sienna Transmission Service

The transmission delivers power from the engine to the wheels so that you can drive on your terms. Because your transmission is responsible for converting the right amount of power into the right amount of speed, a small transmission issue can put a big dent in your Sienna’s performance. 2018 Toyota Sienna transmission issues could include shifting delays, grinding or jumping during acceleration, a feeling of shakiness, or whistling noises and a burning smell coming from under the hood. Let Toyota Sienna transmission problems linger and you might notice your fuel economy decrease or find that you can't drive your Sienna at all. Our expert techs are familiar with 2018 Sienna services and perform them according to Toyota-recommended specifications. Schedule an appointment at your local Firestone Complete Auto Care at the first sign of transmission problems to help keep your Toyota running for miles and miles.

Questions About 2018 Toyota Sienna’s Transmission

  • Does my Sienna's transmission fluid need to be inspected?  Maintaining your Toyota Sienna transmission fluid is one of the best ways to maintain your transmission's health. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Toyota. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can transmission fluid leak from my Toyota Sienna?  Yes. Toyota Sienna transmission fluid can leak over time and potentially cause transmission issues.
